Mastering PowerShell: Output a Comprehensive List of CSV Records in a Text File

When working with CSV files in PowerShell, you might want to quickly analyze the data they contain. One common requirement is to list all the CSV files in a directory along with the number of rows present in each file. If you've come across the issue where only the first file's information is being output to your results file, you're not alone. In this guide, we'll tackle this problem together and show you how to produce a detailed report of CSV files with their respective row counts in a text file.

The Problem: Incomplete Outputs

If you're running a PowerShell script to gather CSV file information but only see the details for the first file in your output, it can be frustrating. The initial script you may be using likely looks something like this:

Here, the script takes the data from the first CSV file and logs the file name and row count, but it doesn’t iterate properly to save the details of subsequent files into your output file.

The Solution: Enhancing Your Script

To resolve the issue, we need to streamline the process so that the script handles all CSV files and accurately compiles their names and row counts into a single output file. Here's an improved version of the script:

Breakdown of the Solution:

Get-ChildItem: This cmdlet retrieves all the CSV files from the specified directory, including any files in subdirectories due to the -Recurse flag.

Select-Object: This allows us to add a calculated property (Number of Rows), which calculates the total number of lines in each file, correctly decreasing by one to exclude the header row.

Export-Csv: Finally, we use this cmdlet to export the information to a CSV file. This will allow for cleaner and easier data handling compared to a plain text file.

Final Output

You’ll now have an output.csv file stored in C:\test\, which lists all CSV file names and their corresponding row counts in a structured format. You can open this file using any spreadsheet software, making your data easy to read and analyze.

Conclusion

By following the enhancements outlined above, you can efficiently output a comprehensive list of all CSV files along with their respective row counts. This approach not only enhances your productivity but also elevates the quality of your reports. PowerShell provides a powerful interface for managing file data, allowing you to easily gather insights from your datasets. Happy scripting!
